Behaviour & Temperament
Bearded Cory is a peaceful species (2/10), while Clown Pleco (L104) is generally mild-mannered (3/10). This modest difference means Clown Pleco (L104) may occasionally assert dominance over Bearded Cory.
Bearded Cory and Clown Pleco (L104) both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.
Worth noting: Clown Pleco (L104) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Bearded Cory and Clown Pleco (L104) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.
Water Parameters
The safe temperature window for both species falls between 23°C and 23°C. Aim for the midpoint of this range (around 23.0°C) for optimal comfort.
Both fish can tolerate a pH between 6 and 7.4. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 4–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Bearded Cory and Clown Pleco (L104) together, plan for an aquarium of at least 110 litres with a minimum length of 90 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Sand (Sifters), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

What water temperature is best for Bearded Cory and Clown Pleco (L104) together?
Keep the aquarium between 23°C and 23°C. A target of around 23.0°C sits comfortably within both species' preferred ranges.
Are Bearded Cory or Clown Pleco (L104) aggressive?
Bearded Cory is peaceful (2/10) and Clown Pleco (L104) is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Bearded Cory and Clown Pleco (L104) need?
Both species overlap in the 6–7.4 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Clown Pleco (L104)'s territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Clown Pleco (L104) space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
Does Clown Pleco (L104) being nocturnal affect compatibility?
Clown Pleco (L104) is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Clown Pleco (L104) during evening hours.
